我最喜欢的小动物是小猫,我们家就养了一只小猫,它是邻居送过来的。因为现在那只小猫已经死了,所以我会经常想起它。

My favorite little animal is a kitten, and we have a kitten in our house. It was sent by a neighbor. Because the kitten is dead now, so I often think of it.

小猫长得很漂亮,他有一身雪白的毛,爪子下的肉垫可以使他走路没有一丁点声音。最独特的是他的眼睛:一只眼睛是蓝色的,另一只眼睛是绿色的。蓝眼睛像蓝宝石,绿眼睛像绿宝石。

The kitten was beautiful. He had a snow-white coat, and the pads under his paws made him walk without a single sound. The most unique is his eyes: one eye is blue, the other eye is green. Blue eyes are like sapphires, green eyes are like emeralds.

小猫很贪吃,有时一斤重的鱼不一会儿就“消灭”了。有一次,妈妈做了一碗鱼汤。小猫跳上桌子,津津有味的吃了起来。正在吃的时候,它被我发现了,于是我狠狠的教训了他一顿。小猫耷拉着脑袋,好像在说:“我再也不敢了。”我立刻笑了。

Kittens are voracious, and sometimes a pound of fish will soon be wiped out. Once, my mother cooked a bowl of soup. The cat jumped onto the table and ate it with relish. While I was eating, it was discovered by me, so I gave him a hard lesson. The little cat drooped its head as if to say, "I dare not."." I laughed at once.

现在那只小猫已经死了,从那以后,我每次见到小猫,都要和它嬉戏一番。小猫,你到底去了哪里了呢?

Now that kitten has died, since then, every time I see a kitten, I have to play with it. Kitty, where the hell have you been?

Animals are mans most loyal friend, please dont hurt them.

I am particularly fond of small animals,. I think, they are mans most loyal friend. So, when I see others to dispose of animals, in the heart can not help but sad. My dream is to people and animals live in peace.

Now people are like to eat dog meat hot pot, I dont understand. A dogs life, it is to his own master, dont just because it is old, useless, and denied the value of its existence. This is not possible! People will also newborn puppies thrown into the lake, trash can, they are discarded, it is no good. Everyone has the right to existence significance and value, even if is a person, also not qualified to deprive their lives.

I have witnessed the cat after being hit by a car fly. The distorted face telling the pain of it. Its blood, viscera was hit from in vitro. Although the rain wash away the traces of blood, but every time I go there, mind will automatically jump out of the scene, think of the cat that broken beyond recognition, think about it before he died not look in the eyes...

Since then, I was in my heart silently vowed, to do their own efforts, to protect small animals, at least, dont let them innocent caused the death.

I think, in the future, I will set up a "happy family", there will be dedicated to adopt the stray animals, if the man willing to adopt, I will also be given to him. In this way, those who stray cat, stray dogs have a warm home. I will also for those precious endangered animal donations, not completely destroy them.

Perhaps, so I am very silly, very silly, but I am willing to do that silly to worry about in others eyes puny little animals.

If you also like me "stupid", let us firmly "silly". Because they are lovely.

动物是人类最忠诚的朋友,请不要伤害他们。

从小,我就特别喜欢小动物。我觉得,它们是人类最忠实的朋友。所以,当我看到别人随意抛弃动物时,心中不禁很难过。我的梦想就是人们和动物和平相处。

现在人们都很喜欢吃狗肉火锅,我很不理解。狗的一生,都是为了自己的主人,难道就只是因为它老了,不中用了,就否定它存在的价值。这是不可以的!人们还将刚出生的小狗崽扔到湖里、垃圾桶里,将它们随意丢弃,这也是不行的。每个人都有存在的意义和价值,即使是人,也没有资格剥夺它们的生命。

我曾经亲眼目睹了猫被车撞飞后的惨状。那扭曲的脸诉说着它的痛苦。它的鲜血、内脏被撞离体外。尽管雨水冲刷掉血的痕迹,但每当我走到那儿时,脑海就自动地跳出了那一幕,想起那只被撞得面目全非的猫,想起它死前不甘的眼神……

从那时起,我就在心里默默发誓,要尽自己的努力,来保护小动物,至少,也不会让它们无辜枉死。

我想,在将来,我会成立一个“幸福之家”,这里会专门收养流浪小动物,如果好心人愿意收养,我也会赠送给他。这样,那些流浪猫儿、流浪狗儿就有了一个温暖的家。我也会为那些珍贵的濒临灭绝的动物捐款,让它们不至于完全灭绝。

或许,这样的我很傻、很傻,但我愿意做那个傻傻的为在别人眼里微不足道的小动物担心的人。

如果你也像我一样“傻”,那让我们坚定不移地“傻”下去。因为它们都是可爱的。

喜欢的小动物是海龟,它有一个圆圆的脑袋,可以在龟壳里自由伸缩。它有一个厚厚的外壳,那个壳既像是它的家,又像是它的盾牌,可以阻挡危险,保护自己。它的脚不像乌龟那样有一个个小爪子,而是像扇子一样扁平扁平的。在海洋里,它能像鱼儿一样在水中随心所欲地游来游去,这与它像扇子一样的脚有很大关系。海龟只有离开水后便爬着走,那速度才是真正的龟速。

My favorite small animal is the turtle, which has a round head and can flex freely in the shell. It has a thick shell, which is like both its home and its shield. It can stop danger and protect itself. Instead of having a small claw like a tortoise, its feet are flat and flat like a fan. In the ocean, it can swim freely in the water like a fish, which has a lot to do with its fan-like feet. Turtles only crawl away from the water, and that#39;s the real speed.

海龟产卵的时候不像其它动物妈妈一样产完卵就不管了,而是用沙子将卵藏好,以防其他动物偷吃,真是一位贴心的妈妈。它们的窝更是奇特,别的动物的窝都是用沙土堆起来或是在陆地上打一个洞,而海龟则是在海底打一个洞住进去。小海龟出生一个月后,海龟妈妈就不会再管自己的宝宝了,而是让它们自己生活下去,让它们学会自己成长。

Turtles do not lay eggs like other animal mothers. They hide eggs in sand to prevent other animals from stealing them. It#39;s really a kind mother. Their nests are even more peculiar. Other animals#39;nests are piled up with sand or made a hole in the land, while turtles make a hole in the sea floor. One month after the birth of the baby turtle, the mother of the turtle will no longer take care of her babies, but let them live on their own, let them learn to grow up.

这就是我喜欢的动物,海龟。

This is my favorite animal, the turtle.

关于保护动物高中英语作文1:Animals Need Protecting

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

关于保护动物高中英语作文2:Protect animals

I am a student from Xinhua High School in Chongqing,China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind,nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately,such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

关于保护动物高中英语作文3:How tu protect animals

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

Animals Need Protecting

It is suggested that people have been aware of the issue--lack of preservation for endangered spieces, animals and plants, but as you see , they placed little efforts to cope with the problem.despite the versatility and intricacy of instruments , I would pore over some of the most striking ones and offer alternatives afterwards.

One of the major reasons , causing peoples inocence of protecting animals, is that the government did not function well as an educator, arosing peoples initiative in shielding wild animals, which led to the consequence that people do not know their responsibility to prevent animals from dangers, and specific knowledge in guarding them. what is equally important as the reason mentioned above is that media did not meet our satisfaction to inform the mass of the emergency which is crutial in arousing peoples conciousness to keep animals safe.

In spite of the serious problem, measure leading to profound improvement still can be taken. owning to the fact that funds are insufficient in some developing countries, developed countries or international organizations should shoulder more burden -- finacing them in order to capacitate them to accompolish the protection of animals. at the same time, education in telling people the way to make animals harboured ought to be focused on, thus resulting in peoples better awareness in the camouflage of our pla#from cutest creatures.

It is belived by me that if correct actions are taken to preserve animals, any kind of them will be far away from extinction forever.

篇18:写濒临危机动物的英语作文北极熊

全文共 3755 字

+ 加入清单

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后,北极熊就会出发去寻求它们最喜欢的食物:富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹,所以它们进入禁食期。至少,情况应该是这样。但是由于地球变暖,温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为,北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求,进而生存下去,这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论,即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究,还有早期的探险者日志,我们很早以前就知道,北极熊会以陆地食物为食。但是辩论的焦点在于,这些食物是否能增加北极熊的能量。”换句话说,这些替代食物能否为北极熊提供足够的营养,弥补不能进食海豹带来的损失?

为了解开这个疑惑,皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算,从表面上看,北极熊在这段时间食用了陆地食物。随后,他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间,北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”,但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明,陆地食物不能为北极熊提供足以抵消大量损失的能量。所以,北极熊可以从食用海冰下面的食物转向食用陆地食物,并帮助它们对抗日益延长的无冰季这个观点,并没有在这项数据中得到证明。”

问题是,北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础,而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是,将脂肪吸收进它们的系统中,然后把这些脂肪放在身上以增加体重,这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育,它们必须要去猎食,可是它们不能在漫长的无冰季期间一直不进食。所以,随着北极地区变暖,较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

兔子很讲卫生。他今天在这里上厕所,明天还会来这里上厕所。

兔子喜欢吃青菜、萝卜……。兔子一般不喝水,因为菜里面含有许多水分,吃了菜就等于喝上水了。

nimals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

动物是自然资源,在整个历史过程中,人类一直在糟蹋着这种资源。人们杀死动物,获得它们的皮毛,把它们当作食物或运动方式,或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。

为什么人们应该感到担忧呢?因为我们需要动物,因为它们一旦消失,就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来源。在维持自然平衡中,每种动物都有其作用。毁灭某种动物会导致许多问题。比如,农民们如果杀死为数众多的鹰,他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么?因为鹰吃鼠类,没有鹰控制它们的数量,鼠类就会迅速繁殖。

幸运的是,有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法

律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。
